Question

In a nuclear reaction, mass must be lost to produce energy.

Answer 1

either in fission or fusion there will be a loss energy from the nucleus..so true..

Answer 2

Answer

● The statement that is true about nuclear reactions is that they follow Einsteins equation which allows the conversion of mass to energy.

● Einstein’s mass - energy equation gives the idea that energy and mass are two inter convertible forms of the same thing.

● This equation clearly answers the question about the large amount of energy produced by produced in nuclear reaction even though they don’t involve very heavy atoms.

Formula = { E=mc^2 }
